This invention relates to a cushion or insert to anupper or lower holding frame 0 or d. for mattresses or the like consisting of spiral The insert or spring cushion is covered in springs placed the one at the side of the known manner by a cover 7, on which the othe i bolster is placed which is not shown in the The novelty consists essentially in that drawing.

the springs forming the insert are each pro- As shown in Fig. 2 each spring a is extendvided or formed at the upper and lower ends ed at its upper and lower ends and is bent with integral rings, the rings being located to form lateral ringsa or a", the ends g-of at the side of the spring and serving as means the rings being provided with eyes or hooks for connecting adjacent springs with each which are fixed to the original spring a. The 55 other.' The connecting rings .of the springs ends 9 are connected to the springs underare preferably formed by bending at least neath the upper and above the lower surfaces one of the upper and lower windings, the ends formed by the extreme windings of the origiof the rings being preferably hooked into or nal spring a, so that any contact between 5 connected to the windings of the springs at the ends 9 and the cover 7 resting on the ex- 60 points located inwardly of the upper and treme windings of the spring a is avoided lower surfaces of the insert. in a simple manner. The rings a and a A resilient cushion or insert formed in this are preferably formed, from the original manner is smooth on its upper and lower surspring a at the top and at the bottom by a.

faces owing to the fact that no knots, hooks reverse bend of 180. The rings a and a" or other connections between the springs are serve for holding and staying of the adjacent exposed. The insert, moreover, may be made complete springs a the wire windings of by hand in a simple manner without any which engage with the rings a and a. As special machines or tools. The insert is light shown in Fig. 1 the springs a are arranged in weight and can be economically manufacn staggered relation o eac other. 7o tured being, as a matter of fact, lighter than In his manner an insert, consisting of a the usual insert due to the employment of a plurahty of separate spiral springs 11, is pro-' smaller number of complete springs, every duced whlch, on the one hand, is perfectly other spring only being of full length. smooth on the upper and lower surfaces Th b di t f th i ti are which come into contact with the cover 7 and ill t t d b w ef example i th free from knot formations or free ends which companying drawing in which: easily might damage the cover The new Fig. 1 shows the insert in top plan view, insert 1s further distlngulshed 1n that it 1s the cover beingpartly out 1f of simple construct1on and can be made by 35 Fig, 2' how i r ti i one i l hand. Owing to the use of a small number rowof spring A -A of th Fi 1, of complete springs, t presents further the Figs. 3 and 4 illustrate two modifiedforms advantage of g w g a cheapness and .of construction on asmaller scale. of possessing a specially soft yleldability.

The resilient insert consists of a plurality The invention is evidently not limited to 49 of spiral springs a all of the same heightarthe forms of construction shown, for as ilranged vertically side by side, the windings lustrated in Figures 3 and 4, various'modifiof the spiral springs on the outer circumcations arepossible. The two bent off rings ference of the insert, which is for instance a and a" may be arranged for instance so of rectangular shape, being attached by that, instead of extending both in the same means of sheet metal clamps b or the like direction, they extend in opposite directions,

. composed of a number of vertically disposed i. e. are lying on two opposite sides of the orilginal spring.

t is further possible, especially on springs which have more than the four windings shown in the drawing, to use a double winding ring a for the mutual supporting in stead of the simple ring. For instance, as shown in Figs. 3 and 4, instead of one single ring on each end of the spring, two windings of the original spring can be bent off in the manner above described. In this case the knot or hook-shaped end fixation is lying farther in the interior of the insert.

I claim:

1. An insert for mattresses or the like,

spiral springs, arranged in longitudinal and transverse rows, each spring having at its upper and lower end a ring integral with the spring,-situated on the outer side of the spring axis, and serving as binding means for a plurality of adjacent springs, and to form with the springs substantially unbroken top and bottom surfaces.

2. An insert for mattresses or the like, composed ofa number of vertically disposed spiral springs, arranged in longitudinal and transverse rows, each spring having at its upper and lower end a connecting ring integral with the spring and disposedto, one

side of the spring axis, said connecting rings being formed by at least one of the originally uppermost or lowermost spring windings bent away approximately 180 degrees from the respective springs, and said rings being effective to bind a plurality of adjacent springs together and to form with the springs substantially unbroken top and bottom supporting surfaces for the insert, the ends of the rings being connected by hooking or tying with the windings of the original respective spring between the upper and lower surfaces of theinsert.

3. An insert for mattresses or the like comprising a plurality of spiral springs arranged side by side, each spring being spaced from the adjacent springsv by approximately the width of a spring and being connected by rings formed as a continuation of one of the adjacent springs, and extending over the space between adjacent springs.

4. A11 insert for mattresses or the like comprising a plurality of spiral'springs arranged side by side, each spring having an end convolution disposed to one side of the spring axis and connected to an adjacent spring at a point disposed inwardly of the outer surfaces'of said end convolutions, to

fo m a substantially continuous supporting surface for the insert.

5. An insert formattresses or the like, comprising a plurality of spiral springs arranged side by side, each spring having an end convolution of a diameter substantially that of the spring, disposed ,to one side of
